Somatic dysfunction and the phenomenon of visceral disease simulation: a probable explanation for the apparent effectiveness of somatic therapy in patients presumed to be suffering from true visceral disease.

Background And Objectives: Several theories have been put forth in attempts to explain the possible mechanisms by which patients presumed to be suffering from any of a variety of internal organ diseases are occasionally found to respond quickly and dramatically to therapies delivered to purely somatic structures (e.g., spinal manipulation).

Analysis of dynamic standing foot force patterns in a normal male subject by characterization of microvector weight transfer sequences.

Previous foot forceplate analyses in our laboratory have shown that postural sway in a normal male subject induces net weight transfers (microvectors) which have preferred directionalities, and that eye closure is characterized by increases in both the occurrence and magnitudes of these preferred microvectors. The same data generated from 8 x 8 blocks of eyes-open and eyes-closed trials were reanalyzed to examine microvector temporal sequences (i.e.

Power spectral and microvector frequency analysis of dynamic standing foot force patterns in a normal male subject.

Power spectral and microvector frequency analyses of dynamic standing foot force patterns in a normal male subject were performed using a multiple-trial experimental protocol. Power spectral analysis of eight eyes-open vs. eyes-closed 50-sec trials revealed significant power increases in the 0.
